That's a good question.
I guess in some cases you might want the whole
program to sleep, and in other cases you might want only
the current task to sleep. 

To make just the current task sleep, you could code
something like:

task_schedule(task_self(), {3, 3})
     task_yield()

This would make the current task sleep for 3 seconds,
while allowing other tasks to run. You could even wrap
this into a useful routine (task_sleep(n)?)

Since, even when multitasking is used, it might be useful 
to make the whole program sleep, I'll leave sleep() 
as it is, but I'll document this issue.
